What to check before buying a 2021 T-Roc R S-A

Before buying a 2021 Volkswagen T-Roc R S-A, focus on the areas it most often fails on. Tyres accounted for 4.2% of tests for this year.

Tyres (4.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Lighting & signalling (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Seat belts & restraints (0.5% of tests): Belt damage or faulty pretensioners — usually straightforward but safety-critical. Typical repair: £50–£300.

Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
